PEGGING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 423,921, dated March25, 1890.

lpplioation filed November 19, 1888. Serial No. 291,262. (No model.)

To all whom it may concern:

Be it known that we, CHARLES S. GOODING, of Brookline, county ofNorfolk, and SHERMAN W. LADD, of Somerville, county of Middlesex, andCommonwealth ofvMassachusetts, have invented certain improvements inmechanism for separating and distributing tacks, nails, screws, buttons,and other articles adapted to be suspended by their heads or enlargedportions, of vwhich the following, taken in connection with theaccompanying drawings, is a specification.

This invention relates to mechanism for separat-ing and distributingtacks and nails and other articles-such as buttons, eyelets, rivets,screws, zc-that have heads or enlarged portions whereby to be suspended,as hereinafter more fully explained and described.

The invention is now employed by us as a component part of alasting-machine for the purpose of separating and distributing tacks.Said lasting-machine formsthe subject-matter of a separate applicationfor Lett-ers Patent to be iiled in the United States Patent Oiiicesimultaneously with this application, Serial No. 291,263. In thatapplication this invention is shown in connection with a tack-drivingmechanism, and reference thereto may be had for a description of its usein connection with such mechanism.

Referring to the drawingsFigure 1 is a side elevation representing -amechanism embodying this invention, and specifically designed forseparating and distributing tacks. Fig. 2 is a section thereof on line 22, Fig. 1. Fig. 3 is a section on line 3 3, Fig. 1, looking toward theright. Fig. 4 is a view on the same line, looking toward the left. Fig.5 is a plan View of Fig.1 with the tack disk or pot made in section, thetop thereof being removed to permit looking into the same. Fig. 6 is asection on line 6 6, Fig. 3, looking toward the left. Figs. 7, S, and 9are details to be referred to and described hereinafter.

The shaft 204 is provided with a spiral gear 205, that meshes with asimilar gearon the main driving'- shaft, from which power isVtransmitted to revolve the shaft 204. The

motion of said shaft is transmitted to the shaft 206 throughintermediate-mechanism contact with the basin 207, which opens at its)rear end into the pot. The tacks are placed in bulk in the basin 207 andpass down its inclined faces into the disk or pot 100 and are lifted byribs 208 on the pot to a point above the pan 209. Said pan is providedwith inclined faces (sce Fig. 4) converging to a point above theracewayin the chute or channel block H. The tacks falling from the ribsstrike into the pan 209 and slide down its faces y y to theraceway-groove 210, and are suspended in the raceway with their pointsdownward and their heads bearing upon the edges of the channel-blockalong the -raceway. The tacks in passing down the inclines of the panare naturally brought in line with the raceway-groove and slide onto thesame, point orhead forward, in either of which cases they hang suspendedin the raceway. Tacks which do not strike in the raceway pass over thesides thereof and fall into the basin, and thence to the pot below, tobeagain lifted and dashed into the pan, as before. Obviously some of thetacks may be improperly sus- Apended in the raceway and tend to obstructthe downward progress of other tacks. These improperly-suspended tacksmust be either lift-ed from `the raceway or adjusted and properlysuspended to pass downward with the others. On the channel-block is abridge 214, which overhangs the raceway. This bridge obstructs thedownward progress of all tacks not properly suspended in theraceway-that `is to say, in other words, a tack must be down upon thechannel-block, its head bearing closely on the surface of the block, itspoint in the raceway, in order to pass under the bridge, and once Vunderthe bridge it is no longer liable to displacement. Above the bridge is atripper-arm 211. This tripper is supported in the rock-shaft 211. Itsbottom end bears upon the channel-block above the racewaygroove, and itsend is preferably grooved to receive the edges of the channelblock, asshown in Figs. 3 and 5. The trip- ICO per permits vertical movementagainst the spira-l spring 213, which is arranged about the shank of thetripper-arm, as shown, and operates to hold it down upon thechannelblock. The vertical movement of the tripper against said springallows it to be reciprocated along the raceway-block and also to bebrought against the inclined end of the bridge 2li, as shown in Figs. land To this end an intermittent rocking movement is imparted to theshaft 212, which carries the tripper, by the revolving pot 10() throughintermediate mechanism composed of the bellerank lever 215, whichengages stops 216 on the pot, and an arm 217 on the shaft 212 for givingmovement to the shaft in one direction, and a spring 21S for returningthe shaft or moving it in the opposite direction. The rearward movementstops the tripper on the incline of the bridge, as shown in Fig. 7. Byreference to said Fig. 7 it will be observed that a tack is representedas improperly suspended in the raceway and impeding the downwardprogress of other tacks. The tripper is engaging and about to moveupward along the raeeway to agitate and readjust the tacks improperlylodged in the raceway. To this end the tripper, after leaving thebridge, is depressed by the spring 213 into contact with thechanne1-block and is moved upward along the channel-block, carryingbefore it the tacks. The tripper is then withdrawn quickly onto thebridge and the tacks are allowed to slide downward along the raceway. Inmany cases the tacks will have been adjusted by a single movement of thetripper so as to pass under the bridge; but a second or third movementthereof will in all cases accomplish the result desired. To this end thetripper is moved forward regularly at intervals, its action beingharmless and of course useless, except when tacks are in condition foradjustment thereby. After passing the bridge the tacks gravitatedownward to a distributing device consisting of the worm or screw-headedshaft Sl, whereby they are separated and drop one by one into thedriver-tube S2 or other receptacle. To

this end said screw-shaft is continuously revolved by a suitablemechanism-as, for instance, by means of shafts 20s 7L and gears c CZ, asshown.

In operating the machine the pot or disk 100 is revolved continuously,and the tacks are lifted thereby above and dashed into the pau 209, andslide thence into the raceway, as before described.

lVe have described this invention and represented the same by thedrawings as embodied in a mechanism for distributing tacks; but we wouldnot be understood thereby as limiting ourselves to a mechanism formanipulating tacks only. Such mechanical Variations in the mechanism asany ordinary mechanic skilled in the art would be able to make with theexercise of ordinary mechanical skill will adapt the mechanism hereinshown and described to distribute and separate other articles capable ofbeing suspended by their heads or other enlarged portions,

substantially as herein set forth.
